The present invention proposes a kind of data back up method based on single-chip microcontroller Flash；
In a kind of preferred embodiment of the present invention, as shown in Figure 1, comprising the following steps:
S10, setting data uses area and backup area in the different sectors of single-chip microcontroller Flash；
In the embodiment of the present invention, such as schemed shown in (a) and figure (b) in Fig. 2, store data using two sectors, one be using area,
One is backup area；Sector auxiliary information: there are address, data ID and CRC check in header data and tail data, the inside；
Flash: flash memory is the one kind for belonging to memory devices, is a kind of non-volatile (Non-Volatile) memory, is not having
Data also can be muchly kept under conditions of electric current supply, storage characteristics is equivalent to hard disk.
Single-chip microcontroller power down leads to the damaged condition using area and backup area when S20, detection data are written for the first time, according to difference
Damaged condition data are repaired；
In a kind of preferred embodiment of the present invention, as shown in figure 3, specifically comprising the following steps:
S201, the single-chip microcontroller power down when first write-in is using area, detection is sky using area's corrupted data and backup area after restarting, then
Area's data will be used to wipe out and re-write sector data again；
In the embodiment of the present invention, single-chip microcontroller is first powered up initialization: when first time use when, sector be all it is empty, upper
The information of sector will be written in electricity initialization the inside；After single-chip microcontroller power down phenomenon occurs, single-chip microcontroller is restarted, judges number
Completely whether according to, partial data judgment mode: header data and tail data are equal, and it is complete for being considered as this data；It is no
Then it is considered damage；
The single-chip microcontroller power down when first time, write-in was using area, system restarting are later empty or sector auxiliary information using area's data
Damage, backup area is also empty at this time, then demonstrates write-in data failure for the first time, at this moment just it is emptied；
S202, the single-chip microcontroller power down after the completion of using area's write-in, it is sky that backup area is detected after restarting, then area's data will be used to replicate
Into backup area；
In the embodiment of the present invention, the power down after the completion of using area's write-in, backup area does not complete the movement of replicate data also at this time, because
This, after restarting system, directly carries out being copied to backup area by what is be written before using area's data；
S203, the single-chip microcontroller power down after the completion of backup area write-in, detect backup area corrupted data, then by backup area number after restarting
Area's data will be used to copy in backup area again again according to erasing.
In the embodiment of the present invention, single-chip microcontroller power down after backup area is completed to be written, then the data of backup area will be damaged, this
When just backup area is wiped, then using area to copy to backup area.
Single-chip microcontroller power down leads to the damaged condition using area and backup area when S30, detection data modification, according to different damages
Bad situation repairs data.
In a kind of preferred embodiment of the present invention, as shown in figure 4, including the following steps:
S301, the single-chip microcontroller power down when modifying data write-in using area, detection uses area's corrupted data, backup area data after restarting
Completely, then area's data will be used to wipe out and restore backup area data；
In the embodiment of the present invention, using there are complete data before area and backup area, fall when modifying data write-in using area
Electricity, after turning back on, system can be detected to be damaged using area's sector auxiliary information, and backup area has complete data, at this moment just
The information for restoring backup area is wiped out using area.Since application is that numerical value is added up and recorded, so losing a unit pair
Systematic influence is little.
S302, single-chip microcontroller power down after modifying data write-in using area, detection uses the data in area and backup area after restarting
Whether ID is identical, if it is different, will then area's data be used to copy in backup area；If they are the same, then equal using area and backup area data
It can be used.
In the embodiment of the present invention, using there are complete data before area and backup area, area is used in modification data write-in
Power down afterwards, after turning back on, system can detect it is different using the data ID of area and backup area because modification data manipulation be
First write using area, thus using the data in area be certainly it is newest, at this moment just the data backup for using area.
In a kind of preferred embodiment of the present invention, the modification data write-in uses area, as shown in figure 5, specifically include as
Lower step:
S3001, area's reading data will be used into the RAM of single-chip microcontroller；
RAM: random access memory, this memory will lose its storage content when power is off.
S3002, modification data；
S3003, data ID is subtracted one；
In the embodiment of the present invention, this is to discriminate between latest data, this situation be if I am using area's data to write rear power down,
The data in that area Liang Ge are all completely, why to subtract one, because data are all 1 after sector erasing.
S3004, it writes data into using area；
S3005, data are copied to backup area.
